To a Tea?

Workers in Montreal have shown that adding boiling water to a single plastic tea-bag releases almost 15 billion micro and nano particles (https://www.theguardian.com/food/2019/sep/27/milk-sugar-microplastics-some-tea-bags-found-to-shed-billions-of-particles ). This scary number is way more than the number of plastic particles that one expected to consume in a year. I suspect that plastic coffee bags will be the same. Loose tea for me!
